 This file lists notable changes in each release. For the full history of all
 changes, see ChangeLog.
 
-2020-12-01: v1.90.7 release
-
-Highlights:
- * vfs5011: Fix possible use-after-free
- * goodixmoc: Add two new PIDs (0x63AC, 0x639C)
- * goodixmoc: Support finger status API
- * synaptics: Only identify within provided prints
- * synaptics: Reject devices with old firmware during probe (#239)
-
-
-2020-12-01: v1.90.6 release
-
-This release is primarily a bugfix release for some older issues.
-
-The major change is that fp_print_deserialize will now correctly return a
-sunken reference rather than a floating one. Most API users will have
-assumed this was true, and issues could happen at a later point.
-If any API user worked around this libfprint bug, they will now leak the
-returned print.
-
-Highlights:
- * Object reference management fixes for FpPrint and identify
- * Fixed issues that caused problem on non-x86 machines (#236)
- * Fix building with older GLib versions
- * synaptics: Support PID 00e7
- * goodix: Fix issue with long USB packages
-
-
-2020-12-01: v1.90.5 release
-
-The 1.90.4 release caused a major regression, as it included a USB hub in
-UDEV the autosupend rule list.
-
-Highlights:
- * Remove USB hub from udev autosupend rules
- * synaptics: Add PID 0x00c9 which is used in some HP laptops
-
-
-2020-11-27: v1.90.4 release
-
-This release contains a number of important bugfixes. On the feature side,
-the USB hotplug support was improved. A lot of drivers received fixes and
-improvements.
-
-Highlights:
- * Work around GUsb cancellation issue
- * Redefine internal image device state machine for more robustness
- * Add public finger-status reporting to FpDevice
- * Rework device removal API to be convenient (#330)
- * Enable powersave for unsupported USB devices
- * Improvements to examples
- * synaptics: Support identify operation
- * synaptics: Fix possible crash when the interrupt transfer is resubmitted
- * synaptics: Add support for PIDs 0x00f9, 0x00fc and 0x00c2
- * elan: Add PID 0x0c4d to supported device list
- * aes3k: Fix driver and add CI test (#306)
- * uru4000: Fix reference counting of image transfer
- * vfs301: Fix driver and add CI test (#320)
-
 2020-06-08: v1.90.3 release
 
 This release mostly contains support for a number of new match-on-chip

+To create a new umockdev test, you should:
+
+ 1. Decide on what to test, the easiest case is just using the existing
+    capture test case.
+ 2. Find the USB device you are testing with lsusb, e.g.:
+     Bus 001 Device 005: ID 138a:0090 Validity Sensors, Inc. VFS7500 Touch Fingerprint Sensor
+    This means we need to record USB device /dev/bus/usb/001/005
+ 3. Run "umockdev-record /dev/bus/usb/001/005 >device"
+    This records the information about device, it should be placed into test/DRIVER/device
+ 4. Run the test, for a capture test this would be:
+      umockdev-record -i /dev/bus/usb/001/005=capture.ioctl -- ./capture.py capture.png
+    This will create a capture.ioctl and capture.png file.
+    Please set the FP_DEVICE_EMULATION=1 environment variable. You may need
+    to adjust the driver to adapt to the emulated environment (mainly if it
+    uses random numbers, see synaptics.c for an example).
+ 5. Place all files into the driver subdirectory test/DRIVER,
+    i.e. device, capture.ioctl, capture.png
+ 6. Add glue to meson.build
+ 7. Test whether everything works as expected
+
+Please note, there is no need to use a real finger print in this case. If
+you would like to avoid submitting your own fingerprint then please just
+use e.g. the side of your finger, arm, or anything else that will produce
+an image with the device.
+
+
+Note that umockdev-record groups URBs aggressively. In most cases, manual
+intervention is unfortunately required. In most cases, drivers do a chain
+of commands like e.g. A then B each with a different reply. Umockdev will
+create a file like:
+
+A
+ reply 1
+ reply 2
+B
+ reply 1
+ reply 2
+
+which then needs to be re-ordered to be:
+
+A
+ reply 1
+B
+ reply 1
+A
+ reply 2
+B
+ reply 2
+
+Other changes may be needed to get everything working. For example the elan
+driver relies on a timeout that is not reported correctly. In this case the
+driver works around it by interpreting the protocol error differently in
+the virtual environment.
